"Somebody's got to stop that boy!" she was shouting, "Rick's troubling everybody in the neighborhood. And he loves to pick on little boys like Danny."
A. Mrs. Green, Danny's teacher, was concerned a lot. "I didn't know that Danny was being picked on," she nswered. "He's never said anything about this to me!" Mrs. Green looked at Danny. "How long has this been going on?" She asked. Danny could only shake his head and look at the floor. He knew if he said a word about this, he would have trouble after school.
